The unique combination of hexafluoroisopropanol (HFIP) employed as solvent and hyperbaric conditions (10–15 kbar) allows unprecedented 1,4-addition of poor nucleophiles, such as aromatic amines, onto sluggish (cumbersome) Michael acceptors without any promoter or workup.
用作溶剂和高压条件(10-15 kbar)的六氟异丙醇(HFIP)的独特组合,使空前的1,4-加成不良的亲核试剂(如芳香胺)可以缓慢地(笨重)地置于迈克尔受体上,而无需任何促进剂或后处理。
